First I followed the video with official instructions, which is quite easy to understand and leads you through the whole process of getting a sample app up and running. I had a problem at first deploying the sample text2speech app, due to an error:

qemu: uncaught target signal 11 (Segmentation fault) - core dumped

But on the second git push attempt it worked (although it takes some time to build all the dependencies). All in all, when I remember the messy steps I had to go through to set up my first RPy image manually, this is super elegant – you don’t even have to use weird dd commands to copy the image to the SD card, it’s enough to just extract the zip file.
